Influence of Potting media and Growth Regulators on citrus seedlings

In potting media experiment the results indicated that Rangpur lime and Australian sour orange rootstock seedlings recorded maximum all growth parameters were recorded in the potting media containing Soil, Sand, Vermicompost @ 1:1:1 v/v, AM, Trichoderma reesei (TCT-10) @ 5g/bag each per bag. However, maximum number of fibrous roots per plant was recorded in potting media with Soil Pressmud + Vermicompost @ 1:1:1 v/v + AM [5g] for Rangpur lime rootstock seedlings. Whereas maximum number of fibrous roots was noticed in the potting media with a combination Soil, Sand, Vermicompost @ 1:1:1 v/v, AM, Trichoderma reesei (TCT-10) @ 5g/bag each per bag. Minimum growth recorded when soil, sand, FYM @ 1:1:1 v/v was used as potting media for both rootstocks. Among different growth regulators tested, to enhance the growth of Rangpur lime and Australian sour orange rootstock seedlings spraying with GA3 @ 200 ppm recorded maximum plant height and SCMR values. Whereas, all growth parmeters of plant were recorded when plants are sprayed with recorded in the IBA root dipping treatments. Lowest values per these parameters have been recorded in control for both the rootstocks.
